get yourself a inlet manifold to suit bike carbs the zetecs run great on them loads of info on LCB forum as many of the guys there running same setup

you should see 160bhp on a healthy 2.0 zetec on bike carbs they are the poor mans webers
megajolt, edis 4 would be needed too for this too.

looks like you bought one of the griffin efi inlets (one from the ginetta) not heard anything good about them tbh
